Abstract
This paper demonstrates how family-building models can be used for checking the quality of abortion data. A family-building model, called FERMODA, is presented and used to check whether the available data on abortion for Hungary are consistent with Hungarian data on other aspects of family building. Model cohorts are generated, using in FERMODA the proportions of women married and the birth and abortion rates of two selected Hungarian cohorts. The estimates obtained from the simulated cohorts concerning use of contraception are compared with the information available on contraception, and, on the basis of this comparison, a judgment is made about the quality of abortion data for Hungary.
